Torque Resisted by One Bolt using Load Resisted by One Bolt Calculator

Torque Resisted by Bolt Formula:

\[ T_{bolt} = \frac{W \times d_{pitch}}{2} \]

Torque Resisted by Bolt (N·m):

1. What is Torque Resisted by One Bolt?

Definition: This calculator determines the torque resisted by a single bolt based on the load it carries and the bolt circle diameter.

Purpose: It helps mechanical engineers and designers calculate the torque capacity of bolted joints in various applications.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ T_{bolt} = \frac{W \times d_{pitch}}{2} \]

Where:

\( T_{bolt} \) — Torque resisted by bolt (N·m)
\( W \) — Load resisted by one bolt (N)
\( d_{pitch} \) — Diameter of bolt pitch circle (m)

Explanation: The torque is calculated as the product of the load and the moment arm (half the pitch circle diameter).

3. Importance of Torque Calculation

Details: Proper torque calculation ensures bolted joints can withstand applied loads without failure, maintaining structural integrity.

4. Using the Calculator

Tips: Enter the load in Newtons, pitch circle diameter in meters, and tolerance percentage (default 5%). All values must be ≥ 0.

5. Frequently Asked Questions (FAQ)

Q1: What is bolt pitch circle diameter?
A: It's the diameter of the circle that passes through the center of all bolts in a bolted joint.

Q2: Why include a tolerance percentage?
A: Tolerance accounts for variations in material properties, manufacturing tolerances, and installation conditions.

Q3: What units should I use?
A: Use Newtons for load and meters for diameter to get torque in Newton-meters (N·m).

Q4: Does this account for friction?
A: No, this is a basic calculation. For precise applications, consider friction coefficients and other factors.

Q5: How do I find the load resisted by one bolt?
A: Divide the total load by the number of bolts in the joint, considering load distribution factors.
